Abstract

V slovenskem visokogorju so suhe južine slabo raziskane. Podatki o prisotnosti suhih južin nad 2000 m nadmorske višine so večinoma iz območja Julijskih Alp. Na območju Kamniško-Savinjskih Alp je večina podatkov do nadmorske višine okoli 1300 m. V naši raziskavi smo pregledali in opisali 160 lokacij od nadmorske višine 1800 m do vrha na območij ih Brane, Planjave, Ojstrice, Turske gore, Rink, Skute, Grintovca, Kočne, Krofičke, Dleskovške planote, Raduhe, Velike in Male Koroške Babe, Kalškega grebena, Kompotele, Mokrice, Storžiča ter na planinah Koren in Kriški planini. Na vsaki lokaciji smo opisali osnovne abiotske značilnosti in značilne rastline ter na tej osnovi opredelili habitatni tip oziroma ekoton med dvema habitatnima tipoma na lokaciji ter vzorčili talne živali. Abiotske dejavnike smo obdelali v obliki opisne statistike, zveze med okoljskimi dejavniki in zastopanostjo vrst suhih južin pa s pomočjo korespondenčne kanonične analize (CCA) in klastrske analize. Primerjali smo podobnost habitatnih tipov glede na abundanco suhih južin. Skupno smo našli 17 vrst suhih južin. Ugotovili smo, da od abiotskih dejavnikov na njihovo prisotnost najbolj vplivata pokrovnost vegetacije in tip tal. Glede poseljenosti s suhimi južinami sta najbolj številčno poseljena ekoton med blazinastim traviščem čvrstega šaša (36.433) in subalpinskim karbonatnim meliščem (61.231) ter ekoton med alpinskimi in subalpinskimi travišči na karbonatni podlagi v Južnih Apneniških Alpah (36.413) in alpinskim karbonatnim meliščem (61.232). Za vrste Mitopus morio, Platybunus bucephalus, Mitostoma alpinum, Nemastoma triste in Dicranopalpus gasteinensis so podatki verodostojni, pri ostalih vrstah gre za ocene, ker smo skupno našli manj kot po 10 osebkov.

Secondary title: ECOLOGICAL INVESTIGATIONS OF HARVESTMEN (ARACHNIDA: OPILIONES) IN THE HIGHLANDS OF THE KAMNIK-SAVINJA ALPS
Secondary abstract: Till recently, in the highlands of Slovenia, the harvestmen (Arachnida: Opiliones) fauna had not been satisfactorily investigated. Sparce data on the presence of Opiliones above the altitude of 2000 m predominantly refer to the area of the Julian Alps, while in the Kamnik-Savinja Alps, the majority most items refer up to the altitude of 1300 m. In our research, were examined for the harvestman fauna and described 160 habitats in the altitudes of above 1800 m till the peak of the following mountains: Mt. Brana, Planjava, Ojstrica, Turska gora, Štajerska, Koroška and Kranjska Rinka, Skuta, Grintovec, Kočna, Krofička, Dleskovška planota plateau, Raduha, Velika and Mala Koroška Baba, the Kalški greben ridge, Kompotela, Mokrica and Storžič, as well as the Koren and Kriška planina mountain pastures. At each site, the basic abiotic characteristics and typical plants were described; on the basis of this data, habitat types and their ecotones, respectively were determined and soil animals sampled. The abiotic factors were evaluated using descriptive statistics, while the correlations between the environmental factors and the presence of Opiliones species were analyzed using the canonical correspondence analysis (CCA) and cluster analysis. The similarities of habitat types with respect to the abundance of Opiliones were elaborated. In total, 17 harvestman species were found. Among the abiotic factors, the vegetation cover and soil type influence most the presence of Opiliones. The highest density of Opiliones was found in the ecotone between the Cushion sedge carpets (36.433) and Butterburn screes (61.213) and the ecotone of Southern rusty sedge grasslands (36.413) and Alpine calcareous screes (61.232). The findings concerning Mitopus morio, Platybunus bucephalus, Mitostoma alpinum, Nemastoma triste and Dicranopalpus gasteinensis are confident, whilst those concerning other harvestman species are rather estimates, as less than 10 specimens were found in total.
